MIAMI – Before Belen Aldecosea flew home to South Florida from college, she twice called Spirit Airlines to ensure she could bring along a special guest: Pebbles, her pet dwarf hamster. No problem, the airline told her.

But when Aldecosea arrived at the Baltimore airport, Spirit refused to allow the tiny animal on the flight.

With her only friends hours away at campus, Aldecosea was stuck. She says an airline representative suggested flushing Pebbles down an airport toilet, a step that Spirit denies. Panicked and needing to return home promptly to deal with a medical issue, Aldecosea unsuccessfully tried renting a car and agonized for hours before doing the unthinkable.

She flushed Pebbles.

“She was scared. I was scared. It was horrifying trying to put her in the toilet,” Aldecosea said. “I was emotional. I was crying. I sat there for a good 10 minutes crying in the stall.”

Aldecosea, 21, of Miami Beach, is now considering filing a lawsuit against Spirit over the conflicting instructions that she said wound up pressuring her into making an anguished decision with a pet certified by her doctor as an emotional support animal. She shared her story with the Miami Herald weeks after the story of an emotional support peacock — denied entrance to a United Airlines flight — went viral on the internet.

This case is much different, said her South Florida attorney, Adam Goodman. “This wasn’t a giant peacock that could pose a danger to other passengers. This was a tiny cute harmless hamster that could fit in the palm of her hand,” he said.

A spokesman for Spirit acknowledged the airline mistakenly told her that Pebbles was allowed. But he denied that a Spirit employee recommended the option of disposing of her pet in an airport restroom.

“To be clear, at no point did any of our agents suggest this guest [or any other for that matter] should flush or otherwise injure an animal,” spokesman Derek Dombrowski said.

After the Nov. 21 incident, Aldecosea said that she e-mailed to complain and that the airline, a few days later, offered her a voucher for a free flight to certain cities. She declined.

Animals on flights have become a lightning rod for controversy in recent years, with some passengers grumbling their fellow travelers are taking advantage of federal law to get humble household pets on planes. From 2016 to 2017, American Airlines recorded an increase of over 40 percent in customers who flew with a service or support animal.

Several airlines have tightened restrictions on service and emotional support animals in recent weeks.

The U.S. Transportation Safety Administration has no problem with carry-on hamsters. “Hamsters are welcome in our checkpoint. Their container would typically go through the X-ray while the owner would hold the hamster as the passenger walks through the metal detector so the creature is not subjected to radiation,” according to TSA spokeswoman Sari Koshetz.

It’s up to airlines whether they allow hamsters on board. Most major carriers such as American, Delta and United, however, don’t allow rodents over concerns about safety and health.

Emotional support animals are usually dogs and cats, but have included squirrels and sheep.

Aldecosea said Pebbles was a true comfort animal and she had her doctor’s letter certifying the rodent. Dwarf hamsters grow no more than 4 inches and weigh less than 2 ounces. A typical cellphone is longer and twice as heavy.

A Miami Beach High graduate, Aldecosea played volleyball at Barry University before transferring to Wilson College in Chambersburg, Pa., last year. It was during her first lonely semester there that Aldecosea developed a painful golf-ball size growth in her neck, leading to a cancer scare.

Frazzled that fall, Aldecosea decided she needed a distraction. At a Pennsylvania Petco, she bought calm and quiet Pebbles. The hamster lived in her dorm room in a small plastic cage with a green spinning wheel, always scurrying to the front of the cage to greet her owner.

“She was so loving. It was like she knew I needed somebody,” said Aldecosea.

In November, Aldecosea learned the growth was benign, but it was still painful. Withdrawing from school and going home hoping to have it removed, Aldecosea booked a Spirit flight from Baltimore/Washington International Thurgood Marshall Airport to Fort Lauderdale, Fla.

Several days before, she twice called Spirit to verify that the hamster could fly. The representative told her it was fine — an assurance that Spirit, after reviewing the conversations, agrees was given to Aldecosea.

“Our reservation representative, unfortunately, did misinform the guest that a hamster was permitted to fly as an emotional support animal on Spirit Airlines,” spokesman Dombrowski wrote in an e-mail.

When Aldecosea showed up that day, she said, the first Spirit agent checked her emotional support pet in with no problem. Pebbles was in a small cage that fit regulations for carry-on luggage.

“They gave me the wrong information more than once,” said Aldecosea, now a student at Texas State University.

But as she walked toward the security checkpoint, a second Spirit employee chased her down, hollering that rodents were not allowed. She said Spirit agents told her she could not put the hamster in the cargo hold either.

After hectic discussions, an outraged Aldecosea accepted a flight later that day to try and figure out what to do with Pebbles. But she had no friends or family in town to pick up Pebbles. It was then, Aldecosea insists, that an employee suggested letting Pebbles go free outside or flushing her down the toilet.

For hours, Aldecosea said, she struggled with what to do. She contacted at least six rental car agencies, but no cars were available during the busy holiday season and she wasn’t old enough to rent a car anyway. A Greyhound bus would have taken days to get to South Florida.

With her flight boarding soon, she pondered whether to just let Pebbles free outside. She said she considered it more humane to end her life right away, and not let her run around scared in the cold, only to die getting hit by a car.
